Major Production Facilities


Nanyo Complex

Tosoh was established in 1935 in Yamaguchi prefecture, on a site which has been expanded and is called the Tosoh Nanyo Complex-a sprawling 3.7 million square meter facility, that is today one of Japan's largest fully integrated chemical manufacturing complexes.

The Complex boasts the largest in-house generating facility in Japan, capable of generating up to 829,000 kilowatts of electricity. Moreover, Tosoh's own port facility is capable of handling 48,000-ton cargo ship. Here at the complex, Tosoh initially began producing soda ash; later expanding its production line to include such products as caustic soda, chlorine and chlorine derivatives such as VCM, PVC, chloroprene rubber, and ethylene amines, among others.

Yokkaichi Complex

Here within Tosoh's second largest production site, Tosoh also produces caustic soda and chlorine derivatives such as VCM and PVC. The combined caustic soda production of both the Nanyo and Yokkaichi complexes make Tosoh the leading producer of caustic soda in Japan. Tosoh is also one of Japan's major manufacturers, producing a fully integrated range of olefin products and derivatives, such as propylene, polyethylene and a variety of petroleum resins here in Yokkaichi.
